Project summaryMonitoring of solar plant performance could be the most efficient when measurements taken at the very source of electrical energy – PV module. Development of a sensor for such application poses technically challenging task due to several restrictions:
Cost of the sensor must be extremely low because it is added to PV-module cost
Cost of the monitoring equipment and installation efforts must be kept low
Maintain measurement precision while working in outdoor environment
As a solution, we developed novel DC powerline communication technology which was granted several patents. Complete traceability of every device achieved through automating of production QA process.
